Foiegras is a powerful opponent, who has extremely strong defences, he's able to take a direct hit from the Wild Liger's Wild Blast and remain largely unaffected. In solo combat, the Knuckle Kong is one of the most powerful opponents faced by the protagonists, outside of the Death Rex.

It often takes several Zoids to defeat the Kong in single combat. When Foiegras fights as part of a team, he proves to be exceptionally effective. Notably, when using the Stegosage's spines as swords, he manages to inflict serious damage to all of team Freedom's Zoids.
